ios - How to make viewcontroller to show as bottom page in ios10 swift3? -

i have 1 view controller button, if click on button should display bottom view controller (like bottom page in android):

i have these 2 demo view controllers, if click on button second view controller should display details view , should popup bottom of first view controller.

thank you.

for achieving should add second view controller child view controller , animate bottom. adding child:

   let secondviewcontrollerinstance = secondviewcontroller() // or storyboard      instantiate method     self.addchildviewcontroller(secondviewcontrollerinstance)     let initialrect = cgrect(x: 0, y: screen_height-200, width: screen_width,                              height: 200)     secondviewcontrollerinstance.view.frame = rect     secondviewcontrollerinstance.view.center.y += 100     self.view.addsubview(secondviewcontrollerinstance.view)     secondviewcontrollerinstance.didmove(toparentviewcontroller: self)     //animate center y     uiview.animate(withduration: 0.3) {         secondviewcontrollerinstance.view.center.y -= 100     } 

tweak heights , widths according requirement.
